VACUUM CONTACTORS

 

Contactor is mechanical switching device having only one position of rest, operated otherwise than by hand, capable of making, carrying and breaking currents under normal circuit conditions including operating overload conditions. Electromagnetic contactor is a contactor in which the force for closing or opening the main contacts is provided by an electro-magnet.

VS Series vacuum contactors are characterized by:
  • Compactness
  • Reliability
  • Environmental compatibility
  • Simplicity
Vacuum contactor is suitable for switching of threephase devices such as electric slip-ring and squirrelcage motors, transformers and capacitor banks. Vacuum contactor series VS is designed, manufactured and tested in accordance with IEC 62271-106.
